  • Page 5: Introduction

    1.0 Introduction 1.1 Scope The FlameGard 5 UV/IR Flame Detector complies with HART Protocol Revision 6.0. This document specifies all of the device specific features and documents HART Protocol implementation details. The functionality of this Field Device is described sufficiently to allow its proper application in a process and its complete support in HART capable Host Applications.

  • Page 6: Device Identification

    Getting Started In order to enable HART communication with the FlameGard 5 UV/IR Flame Detector, users may employ several means including HART handheld communicators or PC-based systems. Using a PC- based software application and a HART interface modem, for example, allow operators to access information from the FlameGard 5 UV/IR Flame Detector.
  • Page 7 PC, host application, or handheld terminal, the master will commonly begin communication to the FlameGard 5 UV/IR Flame Detector by using the HART Command #0. The field device will then respond only if its tag matches. The data in the reply to Command #11 is identical to that of Command #0, so the master can then construct the Unique Identifier for use with further commands.

  • Page 8: Product Interfaces

    Table 2: Analog Output Current Values 4.2.1 Analog Output: FlameGard 5 UV/IR Flame Detector Mode The FlameGard 5 UV/IR Flame Detector Mode is output to the user as the primary variable of the HART protocol. Table 6 shows the interpretation of this variable.

  • Page 9: Device Variables

    The device mode is the variable, which corresponds to the Modbus register 0x00. 6.2 Secondary, Tertiary, and Quaternary Variables: Not Applicable There are none defined for the FlameGard 5 UV/IR Flame Detector. 7.0 Status Information The error status, which is returned via Common Practice Command #48, is shown in Table 3 and corresponds to Modbus register 0x02.
